Filed: 1990-12-19
Abstract: In a photo-setting device, especially a laser exposure device, photographic material (11) in sheet form can be laid inside the device on a cylindrical bed (7). One lateral edge of the photographic material bears against at least one stop (19). An optical exposure system, at least one part of which can rotate about the longitudinal axis (10) of the cylindrical bed and can be moved along it, is thus capable of exposing the photographic material lying on the cylindrical bed. In order also to be able to lay stiffer photographic material, especially printing plates, and photographic material of varying lengths reliably and without damage precisely on the cylindrical bed, there is a transport device (15, 16, 21) for the photographic material parallel to the axis (10) of the cylindrical bed and a guide device with adjustable components (17-20) which press the photographic material lying with its sides parallel to the axis (10) of the cylindrical bed inside against the bed (7) (Fig. 1).

Title: Checking operation of complex systems - by energising signals for individual output units, extensible by hierarchic prefix
Inventor: THURNER HANS DR
IPC: G06F11/34
Filed: 1990-12-19
Abstract: The system comprises eight different processing modules (M1-M8) with a trace point (T1-T8) at each module output. At these points the actual input information which has partly or already completely been processed can be investigated. Triggering of the individual trace points occurs by only three different levels, whereby a specific level concerns outputs in all parts of the system, and a targeted running protocol of individually running processes is not possible. If with the foregoing arrangement it is required to record the processing run, at the end of which the output information of the specific process module (AC) is available, a corresp. trace point (T3) must be triggered with specific prefixes (S,AC). USE - For trace checking processes, etc. permitting checking of several parallel processes with different interpretation.

IPC: H04R5/02
Filed: 1991-02-20
Abstract: In a sound reproduction system (3) for sound reproduction with spatial sound effect at a specific hearing location (10) in a room limited on all sides, in particular the passenger compartment (2) of a motor car (1), loudspeakers (11, 12, 21, 22) are disposed in this compartment in such a way that they generate a spatial sound. To ensure that this spatial sound effect is positioned at a specific hearing location (10), a specific delay time is provided as a basic setting on sound signal delay devices (13, 14, 23, 24) in the loudspeaker channels (17, 18, 27, 28). A considerable fluctuation range exists for the basic setting, within which a change in the spatial sound effect cannot be heard at the hearing location. In addition, this fluctuation range is exploited in order to set the delay times within the fluctuation range in such a way that a smoothing of the frequency response of the sound level at the hearing location is also achieved. <IMAGE>

Abstract: The invention concerns an arrangement of pumps and dispensers for highly viscous liquids with a high solids contents or a content of solids in larger segments, in particular for use with viscous foodstuffs. The substance to be delivered is supplied in a flexible, collapsible plastics container (1). The plastics container is inserted in a pressure vessel (3) connected to a pressure generator (4) which introduces a pressurized medium, in particular air or water, into the space between the plastics container and the pressure vessel. The substance to be delivered is discharged at the end of a delivery tube (7) connected in a pressure-tight manner to the plastics container. The delivery tube is associated with a squeezing device (10-13) comprising a plurality of functionally harmonized squeezing elements which force the substance to be delivered through the delivery tube. The resultant arrangement for discharging viscous liquids is structurally simple and ecological and has optimal microbiological properties.
